Frequently Asked Questions

What is the hepta sodium salt of diethylene triamine penta(methylene phosphonic acid)?

It is DTPMP.Na7 (CAS 22042-96-2, C9H27N3NaO15P5), the heptasodium salt of diethylenetriamine penta(methylene phosphonic acid), an organophosphonate sequestrant bearing five phosphonate groups. RawSource supplies it in bulk as a high-performance chelant and scale inhibitor.

What is the full form of DTPMP.Na7?

DTPMP stands for diethylenetriamine penta(methylene phosphonic acid); the Na7 designation indicates the heptasodium (fully or near-fully neutralized) salt form. It is supplied under CAS 22042-96-2. Request the CoA for active content on a given lot.

What is DTPMP.Na7 used for?

DTPMP.Na7 is used as a multivalent metal-ion sequestrant, a scale and deposit inhibitor in industrial water systems, a bleach/peroxide stabilizer in textile and pulp bleaching, and a builder and chelant in detergents. RawSource quotes it in bulk to water-treatment, textile, and detergent accounts.

Is DTPMP.Na7 soluble in water?

Yes, the heptasodium salt is water-soluble, which suits its use as an aqueous chelant and peroxide stabilizer. See the SDS and technical data sheet for active concentration and dosing guidance.

How is bulk DTPMP.Na7 packaged and quoted?

RawSource ships DTPMP.Na7 typically as an aqueous solution in drums and totes scaled to water-treatment and processing volumes. Pricing depends on active content, packaging, volume, and freight; submit an RFQ with your quantity and ship-to for a current quote with CoA and SDS.
